61347-1 annex L 打高压问题

假设 LED Driver   triple insulatedwrie intransformerSELV output 初次级是打多少


table L4是3000V 但note b:For the construction according to 19.12.3 b) and 26.2.4.1 of IEC 61558-1:2005 test b), the voltage is multiplied by the factor of 1,25.

这是不是打3750V 了

但L9中If, however, insulated winding wires are used for controlgear with an input voltage of up to
300 V, the dielectric strength test voltage is limited to 3 kV for raw material.又是什么意思,打3000V 吗?

到底打多少。

不矛盾啊,你的第一段是针对变压器,第二段是针对原材料
